Beyond Test Day: Supporting Your Child's Journey
Regardless of OC Test Outcomes:
- Celebrate your child's effort and growth throughout the preparation process
- Use developed study skills and habits for ongoing academic success
- Consider alternative educational opportunities if OC placement isn't achieved
- Maintain supportive relationship focused on learning and personal growth
- Apply learned strategies to future academic challenges and opportunities
Alternative Pathways for Academic Excellence: If OC placement doesn't eventuate, the skills developed during preparation transfer directly to other selective opportunities. Many families simultaneously prepare for both OC and private school entry tests like HAST examinations, which assess similar reasoning and analytical skills.
Planning for Future Academic Success: Many families use OC preparation as foundation training for later selective school tests. If your child shows strong academic potential, consider how current preparation builds toward future opportunities like NSW Selective School Tests or HAST examinations for private school entry.
The BrainTree Advantage: Why Strategic Preparation Matters
